Ngo-2023, ukwanda okugxininisiweyo komzi-mveliso wePC yaseTshayina kufikelele esiphelweni, kwaye ishishini lingene kumjikelo wokwetyisa amandla akhoyo emveliso.Ngenxa yokwanda kwexesha eliphakathi kwezixhobo eziluhlaza, inzuzo yePC esezantsi inyuke kakhulu, inzuzo yoshishino lwePC iye yaphucuka kakhulu, kwaye izinga lokusetyenziswa kunye nemveliso yomthamo wemveliso yasekhaya nayo inyuke kakhulu.

Ngo-2023, imveliso yePC yasekhaya ibonise ukunyuka kwenyanga, iphezulu kakhulu kunenqanaba lembali lexesha elifanayo.Ngokwezibalo, ukususela ngoJanuwari ukuya kuMeyi 2023, imveliso epheleleyo yePC e-China yayimalunga ne-1.05 yezigidi zeetoni, ukwanda kwe-50% xa kuthelekiswa nexesha elifanayo kulo nyaka uphelileyo, kwaye umyinge wokusetyenziswa kwamandla ufikelele kwi-68.27%.Phakathi kwabo, imveliso ephakathi ukusuka ngoMatshi ukuya kuMeyi idlule iitoni ezingama-200000, ephinda kabini inqanaba lomndilili wonyaka ngo-2021.
1. Ukwandiswa okuphakathi komthamo wasekhaya kuphelile, kwaye umthamo omtsha wemveliso kwiminyaka emihlanu ezayo ulinganiselwe.
Ukusukela ngo-2018, amandla okuvelisa iPC yaseTshayina akhule ngokukhawuleza.Ukususela ekupheleni kuka-2022, umthamo wemveliso we-PC yasekhaya ufikelele kwi-3.2 yezigidi zeetoni / ngonyaka, ukunyuka kwe-266% xa kuthelekiswa nokuphela kuka-2017, kunye nezinga lokukhula lonyaka le-30%.Kwi-2023, i-China iya kwandisa kuphela amandla okuvelisa ngeetoni ze-160000 ze-Wanhua Chemical kwaye iqalise kwakhona amandla okuvelisa ngeetoni ze-70000 ngonyaka e-Gansu, e-Hubei.Ukusukela ngo-2024 ukuya ku-2027, umthamo omtsha wePC yaseTshayina kulindeleke ukuba udlule kuphela kwi-1.3 yezigidi zeetoni, kunye nezinga lokukhula elisezantsi kakhulu kunangaphambili.Ke ngoko, kule minyaka mihlanu izayo, ukwetyisa umthamo okhoyo wemveliso, ngokuthe ngcembe uphucula umgangatho wemveliso, imveliso eyahlukileyo, ukutshintshwa kwezinto ezithunyelwa ngaphandle, kunye nokwandisa ukuthunyelwa kwempahla kumazwe angaphandle kuya kuba yeyona nto iphambili kushishino lwePC yaseTshayina.
2. I-Raw materials ingene kwixesha lokwandiswa kwe-centralized, okukhokelela ekunciphiseni okukhulu kweendleko ze-industrial chain chain kunye nokuhla kancinci kwinzuzo.

Ngokotshintsho kwi-bisphenol A ekrwada kunye nezixhobo ezimbini ezinkulu zemveliso ezantsi kwiminyaka emihlanu edlulileyo, umahluko kumthamo wemveliso onyukayo nowasezantsi ngo-2022 ufikelele kwelona nqanaba lisezantsi kwiminyaka emihlanu, kwi-1.93 yezigidi zeetoni ngonyaka.Kwi-2022, amandla okuvelisa i-bisphenol A, i-PC, kunye ne-epoxy resin kunye namazinga okukhula konyaka-ngonyaka we-76.6%, i-13.07%, kunye ne-16.56%, ngokulandelanayo, yayiphantsi kakhulu kwi-industrial chain.Enkosi kulwando olubalulekileyo kunye nenzuzo ye-bisphenol A, inzuzo yeshishini lePC inyuke kakhulu ngo-2023, ifikelela kwinqanaba layo elingcono kwiminyaka yakutshanje.

Ukususela kwiinguqu zenzuzo zePC kunye ne-bisphenol A kwiminyaka emithathu edlulileyo, inzuzo ye-industry chain chain ukusuka kwi-2021 ukuya kwi-2022 igxininiswe kakhulu ekupheleni.Nangona i-PC inenzuzo ebalulekileyo yezigaba, umda uphantsi kakhulu kunalowo wezinto eziluhlaza;NgoDisemba ka-2022, imeko yabuyela umva ngokusemthethweni kwaye iPC yajika ngokusemthethweni ilahleko yaba yinzuzo, yodlula i-bisphenol A kakhulu okokuqala (1402 yuan kunye ne-125 yuan ngokulandelelanayo).Kwi-2023, inzuzo yoshishino lwe-PC yaqhubeka idlula i-bisphenol A. Ukususela ngoJanuwari ukuya kuMeyi, i-avareji yengeniso yengeniso yemigangatho emibini yayiyi-1100 yuan / ton kunye -243 yuan / ton, ngokulandelanayo.Nangona kunjalo, kulo nyaka, isiphelo esiphezulu se-phenol ketone sasikwimeko enkulu yokulahlekelwa, kwaye i-PC yajika ngokusemthethweni ilahleko.
Kwiminyaka emihlanu ezayo, amandla okuvelisa i-phenolic ketones, i-bisphenol A, kunye ne-epoxy resins iya kuqhubeka nokwandisa kakhulu, kwaye i-PC kulindeleke ukuba iqhube inzuzo njengenye yeemveliso ezimbalwa kwi-chain chain chain.
3. Umthamo wokungenisa elizweni unciphe kakhulu, ngelixa ukuthunyelwa kwamanye amazwe kuye kwenza ezinye iimpumelelo.

Ngo-2023, ukungeniswa kwe-PC yasekhaya kuye kwancipha kakhulu.Ukususela ngoJanuwari ukuya ku-Epreli, umthamo opheleleyo wokungeniswa kwe-PC yasekhaya wawuyi-358400 yeetoni, kunye nomthamo othengisiweyo wokuthumela ngaphandle we-126600 yeetoni kunye nomthamo wokungenisa elizweni we-231800 yeetoni, ukuncipha kweetoni ze-161200 okanye i-41% xa kuthelekiswa nexesha elifanayo kulo nyaka uphelileyo.Ngombulelo wokurhoxiswa okusebenzayo/okungakhathaliyo kwezixhobo ezithunyelwa kumazwe angaphandle kunye nokukhula kokuthunyelwa kwamanye amazwe kumazwe angaphandle, ukutshintshwa kwezinto zasekhaya phakathi kwabasebenzisi abasezantsi kuye kwanda kakhulu, okuye kwakhuthaza kakhulu ukukhula kwemveliso yePC yasekhaya kulo nyaka.
NgoJuni, ngenxa yolondolozo olucwangcisiweyo lwamashishini amabini axhaswa ngemali kumazwe angaphandle, imveliso yePC yasekhaya inokuba yehlile xa kuthelekiswa noMeyi;Kwisiqingatha sesibini sonyaka, izinto eziluhlaza ezinyukayo zaqhubeka zichatshazelwa kukwandiswa kwamandla, okwenza kube nzima ukuphucula inzuzo, ngelixa i-PC ephantsi yaqhubeka isenza inzuzo.Ngokuchasene nale meko, inzuzo ezinzileyo yeshishini lePC kulindeleke ukuba iqhubeke.Ngaphandle kweefektri ezinkulu zePC ezisenezicwangciso zokulondoloza ukusuka ku-Agasti ukuya kuSeptemba, okuya kuchaphazela imveliso yenyanga, ukusetyenziswa komthamo wasekhaya kunye nemveliso iya kuhlala ikwizinga eliphezulu kakhulu kwixesha eliseleyo.Ngoko ke, kulindeleke ukuba imveliso yePC yasekhaya kwisiqingatha sesibini sonyaka iya kuqhubeka ikhula xa kuthelekiswa nesiqingatha sokuqala.
